Description
Twin Needles are designed for small elongated die applications (≤0.7mmx1.0mm) to reduce the propensity of tilted dies during the ejection process. For elongated dies, single tip needles with one point of contact will create a pivot action and cause the die to see-saw when being ejected.
Our line of Twin Needles are designed and manufactured to the most stringent tolerances. Both twin ejector tips are controlled with a common datum for maximum flatness during the ejection process. Quad Needles come with 0.7mm diameter and will fit into most standard needle holders.
Oricus manufactures a wide range of Twin Needles to fit various die sizes. Pitch-to-Pitch positions start from 0.30mm x 0.30mm and tip radiuses start from R0.015mm. We can customize Twin Needles with additional features according to your die size, process or application requirements.
Features
- Better for small elongated dies compared to Single Needle or Quad Needles
- Comes in Cemented Carbide, HSS and Stainless Steel materials
- For Pierce-Through or small die applications, special sub-micron grade Cemented Carbide materials are available
- Needle Pitch-to-Pitch, radius and diameter are fully customizable according to your requirements
Benefits
- Twin Needle’s 2 point contact with even distribution of force during ejection for elongated dies offers better balance as compared to Quad Needles
- One-time set up of Quad Needles eliminates needle offset issues with multiple single tip needles
- Multiple Twin Needles can be implemented for larger elongated dies (≥1.0mm x 3.0mm) to reduce contact pressure per ejection point while improving overall ejection stability
